According to CIBC World Markets, Equity Research, theFlat Panel Display (FPD) industry has achieved sufficientcritical mass for its growth to explode. Thus, it can nowattract the right blend of capital investments and R&Dresources to drive technical innovation toward continuousimprovement in view quality, manufacturing efficiency,and system integration. These in turn are sustainingconsumer interest, penetration, revenue growth, and thepotential for increasing long-term profitability for industryparticipants. CIBC believes that three essential conditionsare now converging to drive the market forward

This application note describes the implementation of a two-dimensional Rank Order filter. Thereference design includes the RTL VHDL implementation of an efficient sorting algorithm. Thedesign is parameterizable for input/output precision, color standards, filter kernel size,maximum horizontal resolution, and implementation options. The rank to be selected can bemodified dynamically, and the actual horizontal resolution is picked up automatically from theinput synchronization signals. The design has a fully synchronous interface through the ce, clk,and rst ports.

Abstract: As industrial control systems (ICSs) have become increasingly connected and use more off-the-shelfcomponents, new vulnerabilities to cyber attacks have emerged. This tutorial looks at three types of ICSs:programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, anddistributed control systems (DCSs), and then discusses security issues and remedies. This document alsoexplains the benefits and limitations of two cryptographic solutions (digital signatures and encryption) andelaborates on the reasons for using security ICs in an ICS to support cryptography.

The tar file contains the following files: ptfsf.c: heart of the perfect TFSF code ptfsf.h: header file for same ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file fdtdgen.h: defines macros used in much of my code Makefile: simple make-file to compile programs Also include are some simple script files to run the programs with reasonable values. The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
